SPECIFICATION forming part Of "Letters 657,520, dated September 11,1900.

Application filed May 18119005. fierial No. 17,097. (No models To aZZwhom it may concern:

Be it known that I, TONEY'DAVID, a citizen of Germany, residing at NewYork, (Brooklyn,) in the county of Kings and State of, New York, haveinvented certain new and useful Improvements in Saw-Guards, of which thefollowing is a full and complete specification,

such as will enable those skilled in'the art to which it appertains tomake and usethe same.

This invention relates to saw-guards; and the object thereof is toprovide an improved device of this class which is simple in constructionand effective inoperation and which is designed for use in connectionwith'circular saws.

The in vention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which like referencecharacters denote like parts in th several views, and in which- Figure 1is a sideelevation showing my improved saw-guard and the method-of itsoperation; Fig. 2, a plan View, and Fig. 3 a front view.

In the drawings forming part of this speci-' fication I have shown at Aa base or table of a circular-saw support, and at B an ordinary circularsaw. The base or table is provided at C with a slot in which the sawworks, and in the practice of my invention I secure to the said base ortable, rearwardly of said slot, an upright D, with which is connected ahorizontally and vertically adjustable bar or support E, through whichsaid upright D may be passed, if desired, as shown in Fig. 2, or saidbar or support may be made adjustable on said upright in any desiredmanner, and said bar or support E is also preferably connected with saidupright bya set-screw F. A tubular head G or other guard-support ismounted on the bar E and is provided with a setscrew H, whereby saidtubular head or guard support is made longitudinally adjustable on saidbar.

To the lower side of the head G is secured a cross guard-plate L, whichis provided with a central vertical openingM,which opens downwardly bymeans of a slot or opening m, and through which the saw B passes. Thecentral vertical opening M is preferably much larger in cross-sectionthan the opening atm at the bottom thereof, and secured to the rear sideof'said plate is a backwardly and downwardly inclined guard-piece N,which is preferably trough-shaped in cross-section. I may also employ aforwardly-directed and downwardly-inclined guard O, which istroughshaped in cross-section and pivoted to shoulders or projectionsP,con nected with the plate L, as clearly shown, and the free end of theguard O is capable of moving vertically, as will be readily understood,and is normally held in the position shown in full lines in Fig. 1, anotch or recess being formed in the upper edge of the end thereof,adjacent to the plate L, as shown at B, so asto permit of the verticalmovement of the free end thereof.

This device is designed particularly for use in connection with saws fordoing boxwork or other small or fine work, and in practice the operatorstands in front of the saw, so as to guide the work, that portion of theguard shown at 0 being also projected in the same direction. It will beseen that the guard consists of three separate parts-the transverseplate L, the backwardly-directed portion N, and the forwardly-directedportion O-and these parts are connected with the lower end of the head Gin the manner described. The part N is designed to prevent sawdust andother small portions of the material being sawed from being thrownupwardly and forwardly from the back portion of the saw, while thecentral portion L is designed to prevent similar particles or substancesfrom being thrown forward, and the forward portion 0 serves for asimilar purpose and also prevents sawdust and similar material frombeing thrown into the eyes of the operator, and the object of pivotingthe forward portion 0 of the guard is to provide means whereby thematerial being sawed may be raised and adjusted, it being understoodthat there are usually several thickness placed together in operating asaw of this class for the purpose described.

The inwardly-directed lugs or projections in at the sides of the slot oropening min the bottom of the plate L are within the line of the teethof the saw as the saw revolves, and the larger opening M in the plateLabove said lugs or projections affords space for the teeth and permitsof the free operation of the saw; but'the slot or opening m is largeenough to permitof the plate L being passed doivarwardly over the edgeof the saw f-ih placing the guard in position. It will also be'apparcutthat the guard'may be raised and lowered or vertically adjusted, asdesired, by means of the bar E, and the guard proper is a'lsezlongitudinally adjustable on said bar,and I the entire device is simplein construction and operation and well adapted to accomplish the resultfor which it is intended. Having fully described my invention, I
